Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive.
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.
Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 3; UN Pack Group: II
Fireproof. Separated from powdered metals and strong oxidants.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID.
Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical dangers Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Reacts violently with strong oxidants and powdered metals. This generates fire and explosion hazard.
